Problems solved by technology

[0002] Axial Fast Flow CO 2 Laser is currently the most widely used laser in the field of laser metal sheet cutting. Its laser working gas is mainly composed of three gases CO 2 , He, N 2 According to a certain ratio, because the gas ratio of different manufacturers' equipment is different during normal operation, most of the lasers are supplied by discrete gas supply; due to the different proportions of different gases in the laser working gas, The diameters of the three flow valves selected are different, so that the thermal expansion and contraction caused by the change of the operating environment temperature of the valve core and the valve body will have inconsistent effects on the diameter of the throttle valve, so the laser working gas The mixing ratio will also change, which will affect the normal operation of the laser

Embodiment Construction

[0011] exist figure 1 Medium, N 2 Input solenoid valve 1, CO 2 The input electromagnetic valve 2 and He input electromagnetic valve 3 use the same type of electromagnetic valve, so that when they are opened, the flow rate is the same, and they are sent to the mixed gas storage tank 4, and the mixed gas in the mixed gas storage tank 4 is exhausted through the mixed gas storage tank. The valve 8 is sent into the resonant cavity; the mixed gas storage tank 4 is equipped with a mixed gas storage tank pressure upper limit detection pressure switch 6, a mixed gas storage tank pressure lower limit detection pressure switch 7 and a pressure gauge 5, and the pressure gauge 5 is used for Displays the pressure of the gas in the mixed gas storage tank.

[0012] exist figure 2 Among them, the pressure switch 6 for the detection of the upper limit of the pressure limit of the mixed gas storage tank is used for feedback on the upper limit of the pressure of the mixed gas storage tank, a...

Abstract

The invention relates to a fast-flow axial CO2 laser, particularly relates to a method and device for mixing gases, and particularly provides a method and device capable of supplying a proper gas proportion to the split-type air supply fast-flow axial CO2 laser. The invention firstly provides solenoid valves which are of the same type and consistent in path flow. The method and the device provided by the invention can control the mixing proportion of various gases according to opening time or opening frequency of different solenoid valves. According to the method and the device provided by the invention, the inconsistency of the path influence on the solenoid valves can be effectively reduced through expansion caused by heat and contraction caused by cold, so as to further reduce the influence caused by heat and contraction caused by cold on the component proportion of mixed gases.

Description

technical field [0001] The patent of the present invention relates to a method and device for gas mixing, especially for split gas supply axis fast flow CO 2 Lasers provide methods and apparatus for proper gas proportioning. Background technique [0002] Axial Fast Flow CO 2 Laser is currently the most widely used laser in the field of laser metal sheet cutting. Its laser working gas is mainly composed of three gases CO 2 , He, N 2 According to a certain ratio, because the gas ratio of different manufacturers' equipment is different during normal operation, most of the lasers are supplied by discrete gas supply; due to the different proportions of different gases in the laser working gas, The diameters of the three flow valves selected are different, so that the thermal expansion and contraction caused by the change of the operating environment temperature of the valve core and the valve body will have inconsistent effects on the diameter of the throttle valve, so the las...
